To allwhomc't may concern:

Be it known that 1, ABRAHAM Novron, a citizen of the United States,and a resident of New York, borough of Manhattan, in the State of New York, have invented certain new and useful -Improvements in Envelop-Machines,of which .the following is a specification. This invention relates to envelop machines and particularly to those portions thereof which are provided for operating upon the seal and botom flaps of envelops. The object of my improvements is to provide a mechanism of high efficiency at high speed for gumming and folding the bottom flap and for gumming and creasing the seal flap. My improved mechanism while of wide utility in envelop machines in general is herein illustrated a particularly adapted for. operating upon envelope commonly known as catalogue envelo'ps. Such envel ops are commonly provided with relatively ded over onto the body of the envelop and gummed together and with relatively short bottom and seal flaps, the first of which is folded over and gummed to the previously .folded and gummed side flaps,- and the latter of which is creased and may be provided with gum. for sealing. p

In the preferred embodiment of my improvements as herein illustrated Figure 1 is a diagrammatic side elevation partly in sectionof so much of an envelop machine as will serve to suitably show my invention. Figs. 2 to 8 inclusive are diagrammatic side elevations, partly in' section,- of portions of what is shown in Fig. l and in the operation of my improvements. Figs. 9 and 10 are plan views of an envelop partly formed, and completed, respectively, illustrating the op eration of my improvements. Figs. 2 to 8 inclusive are to one scale, larger than the scale of Fig. 1, and Figs. 9 and 10 are to another scale, smaller than the scale-of Fig. 1. in the interest of clarity, as far as possible extraneous features of the machine, such as framing, have'been omitted and the showing confined to the parts directly pertaining to my improvements and to their relative movements.

Rotatable frame 2 is fixed to rotatable shaft 3 and rotatable frame 4: is adjustably fixed to said shaft. Said frame 2 carries specification of Letters Eatent.

- flap folding blade 5, one of folded to the axes of shafts rolls 18 and. 14, the usual guide Patented set. jl't, rare. 200,863.

a coacting pair for folding bottom flap 50, Figs. 10, and gummer 6 for supplying gum gumm-ing said flap to the previously and gummed side flaps 51, 52. Frame 4 earries gummer 7 and creaser 8 for gumming and creasing, respectively, seal of members 9 and for flap 53, Figs. 9 and 10. In their outer and operative positions gummers 6 and 7 travel in a path indicated by dot and dash circle 9. Said gummers may have gum delivered to their peripheral faces by some convenient known means, not shown. Said circle 9 has a diam ter equal to half the diameter of rotatable frame or cylinder 10.

-Said cylinder 10 is fixed'to shaft 15 and carries two'oppositely disposed clips 11 and 12 which coact with blade '5 on frame 2. By suitable gearing not shown frames 2 and 4; are caused to make two revolutions about the axis of shaft 3 for eachrotation of cylinder 10 whereby clips 11 and 12 are brought successively into coaction with blade 5. Dis posed above 'andcontiguous to the field of coaction of blade 5 and clips 11 and 12 are feed rolls 13 and 141- on axes fixed relatively 3 and '15. By suitable gearing, not shown, said rolls are caused to rotate in the direction of their respective arrows at a surface speed equal to the surface speed of cylinder 10. Between feed plate 16 for the partly formed envelop is provided.

To the right of cylinder 10, Fig. 1, fixed to shaft 18, is rotatable cylinder 17, of equal diamter with cylinder 10. Said shaft 18 has its axis fixed relatively to the axes of shafts 3 and 15 and by means of gearing, shown, cylinder 17 fixed thereon is rotated at an equalcircumferential speed to that of cylinder'lO. Said cylinder 17 is provided with oppositely disposed clips, only one offor receiving the.

not.

2 and 3, fixed to shaft 20, rotatably-mounted in the upper arm of bracket 30 of the machine frame, is hub 21 having fixed thereon feeler finger or blade 22. Guide plate 16 is provided with pocket 23 near the lower end thereof, into which the lower end of said finger 22 is adapted to swing, said finger being normally urged thereto by spring" 24. Alsofixed to shaft 20 is pawl 25 for engagement with abutment 26 of gummer cam 27.

' fixed in hub 21 of finger 32 is in the rotative position shown in Fig.

Said cam 27 is pivotally supported on shaft 28 fixed in the lower arm of bracket 30. I

' at its lower end roll 34 for engagement with said cam 32 and has its upper end in engagement with the under side of pin 36, 22. When said cam aron 34, urged by strong spring 37 against arm 33," passes into the depression in said cam and finger 22 is swung out from pocket 23 of plate 16 against the resistance of weak spring 24. This provides a free opening for the entrance of a partly formed envelop 54 between plate 16 and finger .22, Fig. 2. If said finger was not thus lifted the leading end of the swiftly moving envelop or blank would impinge upon said finger and unless that envelop was made of heavy paper, would be liable to mutilation. Immediately after the leading end of the envelop passes said finger 22, cam 32 passes onwardly and roll 34 is lifted and the upper end of arm 33 withdraws from pin 36 and finger 22 is urged by spring 24 against the surface of the traveling envelop without injury thereto, Fig. 3. Said finger 22 is thereby prevented from passing into pocket 23 and pawl 25 is held out of engaging position with abutment 26 of cam 27 Referring further particularly to Fig. 3, gummer 6 is pivotally mounted at 38 on frame 2 and is provided with roll 39 for engagement with the under face of cam 27. Said gummer 6 is urged to its outward position by spring 40 and is prevented from protruding beyond the periphery of circle 9 by arm 41 thereof in engagement with shaft 3. Spring 40 is much stronger than spring 31 of cam 27, and pawl 25 being in its lifted position, roll 39 will pass under and lift cam 27 without disturbing the peripheral position of gummer 6 and which gummer will therefore be in operative position for gumming the envelop when it rotates into engagement therewith, Fig. 6. Seal flap gummer 7 is similarly pivoted at 42 on frame 4 and is provided with roll 43 for engagement with cam 27. Frame 4 may be rotatably adjusted about shaft 3 by loosening set screw 47 whereby the peripheral location of gummer 7 and creaser 8 relatively to gummer 6 and blade 5 may be shifted to accommodate difierent lengths of envelope. Said gummer 7 is urged to its outward position by strong spring44against stop pin 45 in frame 4.

When said roll 43 reaches the upper end of cam'27, roll 39 will have passed out of engagement with the lower end thereof whereby said cam will be permitted to return to the position of Fig. 2 against its stop 29, but the continued presence of blank 54 between plate 16 and finger 22 will prevent pawl 25 from engaging abutment 26, whereby said roll 43 is free tolift cam 27 asecond time, which by the power of strong spring 44 it will do. Gummer 7 will therefore maintain its outward position, Fig. 7. However, if finger 22 encounters no envelop when it is released by cam 32 forcing roll 34 outwardly, said finger will pass into pocket 23 of plate 16 and pawl 25 will engage abutment 26 of cam 27, thereby looking that cam in its inner position. Then when rolls 39 and 43 successively encounter cam 27 they will be forced inwardly toward, shaft 3 and their respective gummers 6 and 7 will be retracted from peripheral path 9 and prevented from depositing gum on the face of cylinder 10, Figs. 1 and 4.

Blade 5 is fixed to shaft 48, oscillatably mounted in frame 2 and said shaft also has fixed thereto arm 49 carrying roll 55 for engagement with fixedcam 56. Said roll is urged to engagement with cam 56 by spring 57,Figs. 5 and 6.

For successively coacting with said blade 5 for folding bottom flap 50, opposite clips 11 and 12 are provided on cylinder 10. As these clips are in all particulars duplicates, a description of one will suffice for both. Clip 11 is fixed to rock shaft 58 pivoted in cylinder 10 and protrudes through an opening or break in the rim of said cylinder. Also fixed to said rock shaft is arm 59 carrying roll 60 for engagement with fixed cam 61. Spring 62 is efiicient for urging roll 60 to engagement with cam 61.

Said cylinder 10 is provided with means for coacting with creaser 8 for creasing seal flap 53 of the envelop. Said means comprises a thin creaser table 63, lying close to Y the unbroken peripheral surface of cylinder 10 and extending lengthwise said cylinder parallel with its axis. Said table is relatively narrow circumferentially said cylinder and may have a groove '64 length-wise thereof for coaction with creaser 8. Said table is carried by one or more arms 65 extending radially from shaft 15 and adjustably secured to said shaft by set screws 66. By this arrangement table'63 may be adjusted circumferentially of cylinder 10 to time said table and groove 64 thereof with oreaser 8. Thus by adjusting frame 4, carrying creaser 8 and gummer 7, about shaft 3, said gummer and creaser may be set nearer to or farther from blade 5 and gummer 6, to accommodate difierent lengths of envelope, and table 63 may be adjusted about shaft 15 to correspond therewith. It will be observed that creaser table 67 is located diametrically opposite table 63 for coaction with creaser 8 during its next suc- 'the horn of cam 56,

611 and clip 11 closes creaser table 63 being adjustable circumferentially of cylinder 10 themutilation of said cylinder face is obviated. It will be ob-' served that creaser 8 is located within circle 9 a distance equal to the projection of the coacting portion of table 63 outwardly from cylinder 10.

For receiving the envelop from cylinder 10 and ironing down the bottom flap, cylinder 17 is provided. Said cylinder has diametrically oppositely disposed clips, as 19 for receiving and gripping the bottom flap end of the envelop, as that end is delivered thereto by clip 11 or clip 12 of cylinder 10. Said clip 19 is fixed to rock shaft 68 pivoted in cylinder 17 and protrudes through an opening in the rim of said cylinder. Also fixed to rock shaft 68 is arm 69 carrying roll for engagement with fixed cam 71. Spring 72 is eflicient for urging roll 70 to engagement with said cam.

The operation of my improved mechanism is as follows: An envelop blank 54, having its side flaps 51 and 52 previously folded and gummed, is delivered bottom flap .50 leading, by feed rolls 13 and 14: over the lower face of guide plate 16 in suitable timing. Just previous to the passage of the leading end of said blank over pocket 23 in plate 16, finger 22 will be, lifted by the passage of roll 34 into the depression of cam 32 and said leading end of blank 54 will pass freely under said finger, Fig. 2. Roll 34 will then promptly pass to the high part of cam 32 and finger 22 will engage the face of blank 54 thereby holding pawl 25 out of engaging relation with abutment 26 of cam In the meantime frame 2 has been re volving in clockwise direction about the axis of shaft 3 and cam roll 39 of gummer 6 will pass under and lift said cam 27, Fig. 3. The leading end of the envelop blank now passes downwardly over the raised end of clip 11 on cylinder 10, and blade 5, pivotally mounted on frame 2, is rotated clockwise on its axis by the engagement of roll 55 with whereby 'said blade is under clip 11, Fig. 5. the low part of cam onto the folded and now leading end of the blank. At the same time roll 55 drops off the horn of cam 56 and blade 5 is withdrawn fromengagement with the blank under clip 11 and leaves that blank in the grip of said clip, Fig. 6.

The continued rotation of cylinder 10 and of the reacting members on shaft 3 will presently bring the mechanism to the position of Fig. '7, wherein seal fiap 53 is being creased by creaser 8 and groove 64 of table 63. T herearward end of said seal flap extends upwardly past gummer 7. Upon the passage of roll 39 from engagement with (am 27. that cam will return against stop caused to tuck flap 50 Roll 60 then passes to clip when said clip is in pin 29 but because of the resence of blank 54 between plate 16 and nger 22 pawl 25 will be unable to lock said cam. Therefore roll 43 of gummer 7 will engage and. raise said cam a second time and gummer 7 will remain in its outward and operative position ready to gum seal flap 53. The continued movement of the mechanism will presently cause said gummer to press the seal flap against cylinder 10 and deposit gum upon said flap.

Cylinder l0 continuing its rotation in anti-clockwise direction, with clip 11 thereof holding folded bottom flap 50 against the face of said cylinder, presently reaches the position of Fig. 8, where roll 60 of arm 59 of said clip encounters a high portion of fixed cam 61 and said clip is raised from engagement with the envelop. Just before said clip releases its hold, roll 7 O of arm 69 of clip -l9 on cylinder .17 passes to a low part of fixed cam 71 and said clip 19 grips the envelop to the face of cylinder 17. As said envelo passes between cylinders 10 and 17, bottom flap 50 is ironed down against the gummed portion of side flaps 51 and 52.

Cylinder 17 continuing its rotation in clockwise direction, conveys the completed envelop away from cylinder 10 and may deliver it by means, not shown, to a suitable receptacle, not shown.

It will be understood that clips 11 and 19 are in difl'erent planes parallel with the view of Fig. 8 for instance, so that they may pass each other without interference.
